The large industrial fan is a large industrial fan with a diameter of 7.3 meters. The blowing area of the fan is directly related to the diameter of the fan. Large industrial fan covers a large area and is easy to clean, which solves the problems of large noise and large energy consumption.

Ten tips for purchasing industrial electric fans

Tip 1: look at the industrial fan in low gear, medium speed gear, especially in high gear rotation, whether the industrial fan motor head and the whole machine will shake? At the same time, listen carefully to see if there are other abnormal noises in the motor head of industrial fan (except for wind noise)? Is the noise level of industrial fan acceptable?

Tip 2: look at the industrial fan after a long time of high-speed rotation (at least 1 hour later) with hands or other devices to sense the heat of the front shell of the industrial fan motor. If it feels very hot, it indicates that the industrial fan motor has poor heat dissipation performance. If the motor temperature rises too high for a long time in the future, it is easy to cause the industrial fan to stop rotating or burn the motor;

Tip 3: look at the speed, power, air volume, noise and other parameters of the industrial fan (in theory, the speed, power, air volume and noise of the industrial fan are directly proportional, that is to say, the higher the speed of the industrial fan, the greater the power, the greater the air volume, the greater the noise, and the better the cooling effect of local ventilation There is a big gap in the measurement of power, air volume, noise and other parameters. In fact, it is difficult to make accurate horizontal comparison. We can only feel it according to our life experience. However, with the progress of science and technology, we can measure the power of different industrial fans with the help of micro power detector to compare which industrial fan saves more power.

Tip 4: look at the high-speed rotation of industrial fan left and right swing head whether there is intermittent pause, whether there is swing head is not in place?

Tip 5: safety performance: to see whether the industrial fan front and rear net adopts dense net design, and whether the overall structure of the product is reasonable? (the industrial fan with dense network design has higher safety performance in the process of use); ask whether this industrial fan is equipped with overheat protector, and whether it will automatically power off when the industrial fan motor is accidentally jammed?

Tip 6: industrial fan motor structure has fully enclosed and open two. High grade industrial electric fan adopts fully sealed motor structure, which can avoid dust and other impurities from entering the motor and attach to bearings, rotors and other parts. The motor runs smoothly and has a longer service life, but the open motor structure is not. Therefore, fully enclosed motor industrial fan is particularly suitable for cotton textile factory workshop or dust and other debris more places to use.

Tip 7: industrial fan bearing oil bearing and ball bearing two kinds. The oil bearing of ordinary industrial fan should be lubricated and maintained regularly. Otherwise, the bearing will be seriously worn, which will produce great noise and affect the service life of industrial fan. However, some medium and high-grade industrial fans are designed with ball bearings, which, like the axle of a bicycle, reduce friction by rolling the ball, increase the speed, prolong the service life of the industrial fan and reduce a lot of trouble.

Tip 8: industrial fan motor material has copper wire, aluminum wire, copper clad aluminum three kinds. The motor with aluminum wire or copper clad aluminum has the worst heat dissipation performance, and the motor with high temperature rise is easy to burn when the industrial fan is running at high speed. The high-grade industrial fan must be made of 100% normal copper wire and silicon steel sheet, which has the best heat dissipation performance, low temperature rise and long service life.

Tip 9: industrial fan blade materials are ordinary plastic fan blade, aluminum fan blade, iron fan blade, ABS plastic fan blade. These four kinds of fan blade materials have their own advantages and disadvantages. However, ABS plastic fan blades are recommended in many places, because the wind blown by them is very cool, natural and fresh, while the wind from aluminum or iron fans is hard and uncomfortable.

Tip 10: industrial fan motor front and rear shell materials are aluminum, copper, iron three kinds. Ordinary industrial fan copper or iron front and rear shell cooling performance is poor, and high-end industrial fan aluminum front and rear shell heat dissipation performance is much stronger than copper, iron, effectively extending the service life of industrial fan.
